Like other iron(II) salts, iron(II) sulfate is a reducing agent. For example, it reduces nitric acid to nitrogen monoxide and chlorine to chloride: 6 FeSO 4 + 3 H 2 SO 4 + 2 HNO 3 → 3 Fe 2 (SO 4) 3 + 4 H 2 O + 2 NO 6 FeSO 4 + 3 Cl 2 → 2 Fe 2 (SO 4) 3 + 2 FeCl 3. Its mild reducing power is of value in organic synthesis. [44]
Lake Okeechobee is heavily polluted and during extreme events releases large volumes of polluted water into the St. Lucie River estuary and the Caloosahatchee River estuary. Loss of Louisiana Wetlands due to Mississippi River levees, saltwater intrusion through manmade channels, timber harvesting, subsidence, and hurricane damage.
An example is zinc oxide, a common paint pigment, which is extremely toxic to aquatic life. [citation needed] Toxicity or other hazards do not imply an environmental hazard, because elimination by sunlight , water or organisms (biological elimination) neutralizes many reactive or poisonous substances. Persistence towards these elimination ...

The means-based evaluation looks at farmers' practices of agriculture, and the effect-based evaluation considers the actual effects of the agricultural system. For example, the means-based analysis might look at pesticides and fertilization methods that farmers are using, and effect-based analysis would consider how much CO 2 is being emitted ...
Hazard analysis and critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level. In this manner, HACCP attempts to ...
The use of biological pest control agents, or using predators, parasitoids, parasites, and pathogens to control agricultural pests, has the potential to reduce agricultural pollution associated with other pest control techniques, such as pesticide use. The merits of introducing non-native biocontrol agents have been widely debated, however.
The agriculture industry is one of the most dangerous occupations and has led to thousands of deaths due to work-related injuries in the US. In 2011 the fatality rate for farmworkers was 7 times higher than that of all the workers in the private industry, a difference of 24.9 deaths for every 100,000 people as opposed to 3.5 deaths for every 100,000 people in the private industry.
