Change in the environment is inevitable and rapid. The cause of the change could be a natural phenomena or life processes. Human activity such as development of agriculture and technology which give rise to widespread industrialization has led to potentially changing environment as a result of pollution culminating in the release of harmful substances such as Agricultural waste, industrial waste, metal scraps, sewage, microbial concentration, oil spills etc. into the soil, water or air. Human environmental intervention as in the construction of dams and diversion of rivers is another cause of change in the environment. Other causes are ozone depletion, Acid rain and acid mine drainage etc. The impact of the changing environment on human health identified in this paper seek to explore the causes of environmental change, effect of human activities on causes of environmental change and effect of changing environment on human health. The findings identified some effects of human activities as outbreaks of infectious diseases leading to human incapacitation and death in severe cases, damage genetic material leading to heritable genetic disorders, malnourishment as a result of wiping out of plants and animal life. Others are skin cancer, reduction of life expectancy etc. some recommendation were made which are Environmental conservation measures, Governments and Non-governmental organizations educating the citizenry.

Interactions of mercury in the environment

88%
Mercury is a pollutant of global concern largely due to its potential for biological transformation into harmful forms and bioaccumulation through the food chains. Mercury is not able to biodegrade in the environment and it forms many toxic inorganic and organic complexes. The strongest harmful effects of mercury concerns the central nervous system. The harmful effects of mercury is very stable, because the mercury compounds bind to enzymes. Getting into the brain, mercury displace zinc from brain tissue, and thus reduces the effi ciency of the brain. Then excreted in the cell nuclei and destroys the genetic material. The antagonism between zinc and mercury partially modifies its toxic effects. Mercury is combined with active groups of proteins and amino acids, accumulating in the body. Selenium has similar affinity, limiting connects these groups with mercury, reducing its toxicity. Antagonists are also cadmium, mercury and zinc, but their effects are most likely related with the action of selenium. Antagonist for mercury is also iodine content in the thyroid gland which is lowered, the excessive concentration of mercury in the body. It is known that taking selenium, zinc and thiols, e.g. GSH and NAC, are of prime importance in considering effects on human organisms as well as the level of its excretion. Due to the fact that interactions are dynamic and poorly understood at present the better understanding of their role requires the further studies. Despite that have been identifi ed interactions between elements and mercury, limiting its toxic effects, we still do not have sufficient knowledge about how to reduce the negative effects of this element on the human body. The definition of what is an acceptable daily dose of mercury for humans also does not quarantee protection of the health, because we do not know the exact limits of tolerance for different follow-up effects of prolonged exposure to low concentrations. It should also be pointed out that the interactions are dynamic and weakly understood at present. The better understanding of the role the afore-mentioned particles may be crucial in the to study the interaction between mercury and various environmental components and to find a substance that interacts with mercury to reduce its toxicity to living organisms.
This work consisted in studying the frequency of deformations of the attachment organ in specimens representing the family Diplozoidae, occurring in roach, common bream, and white bream from live different water bodies. These water bodies differed in morphometric parameters, levels of eutrophication, and character of their pollution. The presence of three types of deformation was stated. The most common were deformations of type II (morphological changes of clamps, such as sclerite deformation, incomplete sclerite separation or sclerites missing altogether in a clamp), while less frequent were those of types I (chaoges in the size of clamps not associated with the structural changes) and III (missing clamps in a set). Most frequently anomalies of the attachment organ were stated in polluted Łyna River, polluted Wulpińskie Lake, and in dystrophic Warniak Lake. Less frequent were anomalies in less eutrophied lakes Dgał Wielki and Ukiel. Also the prevalence values of those parasites were the highest in the polluted water bodies. The present study suppons believes of other authors, that both infection parameters of Diplozoidae affecting fishes and deformations of monogeneans' attachment apparatus can be treated as indicators of environmental pollution.
W pracy przedstawiono przykłady zastosowań roślinności do oceny stopnia zanieczyszczenia różnych elementów środowiska. W pierwszej części przedstawiono definicję biowskaźników i biomonitorów, kryteria ich doboru oraz wady i zalety tego sposobu monitorowania zanieczyszczeń. W drugiej części zebrano przykłady zastosowania typowej roślinności (alg, mchów, porostów, traw, roślin uprawnych oraz drzew i ich części) do oceny stopnia zanieczyszczenia powietrza, wody i gleby.
Quantitative determination of dioctyl the phthalate [bis (2-ethylhexyl) phthalate, DEHP] pollutant in soil and surface water near the "ERG" Factory of Synthetic Polymers located in Wąbrzeźno (Toruń District) has been carried out. Results confirm a high concentration of DEHP in the soil (max. 45 g/kg of air-dry soil). DEHP was also found in the water and bottom muds of Sitno Lake, near Wąbrzeźno (max. 82 mg/kg in wet mud, 0.65 ppm in surface water). Quantification was done using reversed-phase high performance liquid chromatography (RP-HPLC).
The aim of the paper was an attempt at application of multiple- criteria analysis for planning public transport system. Methodological rules of an assessment of public transport systems were presented, including: defining variants and coherent family of criteria. Modelling decision-maker’s preferences and seeking the most desirable solution. The problem of an assessment of public transport systems was formulated as a multiple-criteria problem of variants ranking. Schemes of appropriate communication connections (routes) were developed in the work using GIS technology and subjected to the assessment by means of a coherent family of criteria using the decision maker’s preferences.
Organotin compounds are widely used in almost all sectors of industry. Antifouling paints, which were applied to ship hulls to protect from fouling organisms, are the main source of TBT and TPhT derivatives loaded into the sea. The global ban on the use of these compounds in antifouling systems was introduced by the IMO in 2001. However, the ban did not solve the problem of the use of alternatives to TBT in the ship industry. Moreover, the issue of storing the organotins-containing dredged spoils at sea still remains unresolved. The pollution load deposited in port sediments may become an additional threat to the organisms that dwell in a given water basin. In such cases, it is necessary to establish appropriate norms for the quality classification of dredged spoils. Unfortunately, detailed guidelines concerning the disposal of dredged spoils are still lacking.
Subject and purpose of work: The article presents research aimed at creating the ranking of provinces due to the degree of environmental pollution. The presentation of the spatial distribution of pollutants should result in taking appropriate pro-ecological actions in the provinces. Materials and methods: Secondary material included in the research was the publication entitled “Environmental Protection – Environment 2017” by the Central Statistical Office. The method of ranking diagnostic variables was applied and then a synthetic variable determining the level of pollution in individual provinces was constructed, which made it possible to create their ranking. In the final stage, the author’s own method was implemented in order to divide the provinces into 3 groups. Results: The provinces were ranked from a relatively little to very polluted ones. Three groups of provinces were distinguished according to the criterion discussed. It has been revealed that the third group with the highest degree of environmental contamination includes as many as 8 provinces, that is half of them. Conclusions: The author believes that in order to prepare a more precise spatial diagnosis of the state of the natural environment in Poland, research has to be extended by including adequate information at the county level.
This paper reports on the analysis of polychlorinated biphenyls (PCBs) in selected intercomparison materials (IAEA-435 (tuna) and IAEA-159 (sediment)), and presents the author’s results against the background of results accepted by the organizer of the intercomparison studies, i.e. the Marine Environment Laboratories of the International Atomic Energy Agency in Monaco. The samples were extracted with a mixture of acetone/hexane (tuna) or acetonitrile (sediment) by sonication, cleaned up using micro-columns packed with different materials (e.g. silica gel, florisil, copper), and analyzed by GC-ECD. The difficulties of PCB determination are indicated and the differences between the analyses of low- and high-molecular-weight PCBs are emphasized.
Substances present in soils are of natural or anthropogenic origin. As a result of industrial activity, large quantities of potentially hazardous elements such as heavy metals are deposited in the environment. They may occur as unavailable (similar to the total form), or available for plants. The content of nickel in the soil from the former sanitary zone of the Głogów Copper Smelter does not exceed the Polish threshold values for industrial areas; however, its content may be influenced by other factors such as content of organic matter and soil reaction. In this article we present the results of the nickel pollution in the former sanitary zone of the Głogów Copper Smelter.

Phenol and chlorophenols are long-lived pollutants frequently found in industrial effluents. Phenols are widely used for the commercial production of a wide variety of resins including phenolic resins, epoxy resins and adhesives, and polyamide for various applications. Adsorption process has been proven one of the best water treatment technologies around the world and the removal of diverse types of pollutants from water. However, widespread use of commercial adsorbent is sometimes restricted due to its higher costs. Attempts have been made to develop inexpensive adsorbents utilizing for the reduction of phenol from water. Four types of adsorbent clay, algae, moringa oleifera and rice husk has been used. Among all rice husk shown 97 % of phenol adsorption at 1mm particle size, pH 4, 3 g/l dosing and 150min contact time.
