RNR 1001 : RNR Test 2
Document Summary
As we have talked about; degredation of the planets environment has accompanied human population growth throughout history. Reductions in biodiversity, habitat complexity, biological productivity, and ecosystem process integrity due to human activates. Pollution has contributed significantly to this degradation-substances that are released into the environment that are either toxic, or are released in such magnitude that they can not be processed by affected ecosystems. Acute toxicity results in damage from a single exposure, hydrogen sulfide. Emitted from paper and pulp and asphalt plants, waste treatment plants. Absorbed by lungs, irrigation breathing problems, loss of consciousness, death. Chronic toxicity results from contributed exposure and accumulation of toxic. Worldwide industrial emissions, accumulation in fish and shellfish as methylmercury. =pollutants can be solid,liquid or gasses , and are found everywhere on the planet. Agriculture pollutants include fertilizers, herbicies, pesticides and animal waste. Essential nutrient for plant growth, soluble in water and passes through the soil.
