The chemicals that chemists use can all be helpful to the environment. Many cleaners are based on chemicals that are harmful to consumeboth for humans and other animals and plants in the environment.
The Environmental Protection Agency EPA categorizes many of these chemicals as volatile organic compounds which can be harmful in different ways.
How do chemicals affect the environment apex. Chemicals can enter the air water and soil when they are produced used or disposed. Their impact on the environment is determined by the amount of the chemical that is released the type and concentration of the chemical and where it is found. Aspects of chemical action upon the environment eg.
Effects of natural geo- chemical processes. Corrosion of man-made structures caused by chemical agents. Effects on the biosphere of chemical substances exploited by man.

Pesticide Residues Pesticidesadverse effects. The study of chemical effects in the environment resolves itself into a study of a the levels of a substance accumulating in air water soils including sediments and biota including man and b when the threshold action-level has been reached effects produced in biota which constitute a significant adverse response i. Chemical residues of household chemicals can seep into soils and contaminate groundwater supplies after being disposed of improperly.
Everyday household drugs cosmetics and chemicals are harmful to the reproductive and immune systems of fish and turtles that become exposed to the harmful ingredients. Environmental Protection Agency has awarded an 800000 Science to Achieve Results STAR grant to UC Santa Barbaras Roger NisbetHe will use the funding to develop a model to better understand biological and ecological consequences of exposure to metals nanoparticles and certain flame retardants in industrial and consumer products. How has the work of chemists affected the environment.
A single chemical can sometimes both hurt and help the environment. The chemicals that chemists use can all be helpful to the environment. The work of some chemists causes environmental problems while the work of others tries to fix problems.
Household chemicals are used every day by millions of people to keep things clean fresh and pest-free. Unfortunately we dont realize what harm we are doing to the environment in the process. Agrochemicals usually include plant food several toxic agents pesticides and also in animal farming using antibiotics and hormones.
The application of these agrochemicals has been decisive for crop growth basically for food. Some of the chemicals are prone to cause damage to our environment and ecological balance system. The chemicals can be toxic because they can harm us when they enter or contact the body they can threaten human health The motor vehicle emissions of nitrogen and sulphur oxides cause acid rain which poisons the fish and other aquatic organisms in the rivers and lakes.
POP concentrations increasingly accumulate at each stage in the food web. The highest concentrations are found in apex predators that feed at the top of the food web at a high trophic level. Low temperatures cause POPs to break down more slowly and accumulate in higher concentrations than in more temperate zones.
Combination effects of chemicals. Throughout our lives we are exposed to a variety of chemicals contained in food water medicines the air we breathe cosmetics and health care products shoes clothing and other consumer products. In the natural environment living organisms are also exposed to a complex cocktail of chemical.
Chemicals in our environment Some chemicals can affect mens and womens reproductive health and reduce their chance of getting pregnant. Many cleaners are based on chemicals that are harmful to consumeboth for humans and other animals and plants in the environment. The Environmental Protection Agency EPA categorizes many of these chemicals as volatile organic compounds which can be harmful in different ways.
These chemicals include phosphorous which constitutes about 30 to 40 percent of. Environmental chemicals can cause a broad spectrum of effects which depend not only on route of exposure and dose but on the susceptibility of the recipient of the pollution. Age gender and genotype can have major effects on whether or not an exposure causes a problem.
It can affect soil or waterways and can come from human waste industrial chemicals and other sources. These toxins can exert tremendous effects on the natural world leading to environmental degradation and problems like acid rain and harmful algal blooms in the ocean.
