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]
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.

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 Centers for Agricultural Safety and Health (CASH) are a set of 12 NIOSH-funded agencies focused on occupational health in industry involving food or plant products, such as fishing, forestry, and agriculture. The agencies were established in 1990 under the Agricultural Health and Safety Initiative.
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.
There are four major routes through which pesticides reach the water: it may drift outside of the intended area when it is sprayed, it may percolate, or leach through the soil, it may be carried to the water as runoff, or it may be spilled, for example accidentally or through neglect. [61] They may also be carried to water by eroding soil. [62]
