Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
Indirect effects – organisms directly affected by the loss of food, which has declined due to toxins. Sublethal effects – toxins or compounds that do not induce significant mortality but make the organism sick or make it change its behavior [9] Increased sensitivity to toxicants when additional environmental stressors are present [10]
MeHg is subject to biomagnification and bioaccumulation within marine food webs. [ 4 ] [ 5 ] Cusk are a food source for many other organisms, so the toxins they accumulate over time directly affect any other organism that consumes them, including humans.
Food poisoning, also known as foodborne illness, is a common sickness caused by swallowing food or liquids that contain harmful bacteria, viruses or parasites, and sometimes even chemicals.
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
food miles - the emissions produced and resources needed to transport food and drink around the globe. food security - food produced in sufficient quantity to meet the full requirements of all people i.e. total global food supply equals the total global demand. For households it is the ability to purchase or produce the food they need for a ...
A code orange air quality alert means that air pollution concentrations within the region may become unhealthy for sensitive groups. Not all areas will be affected at the same time due to the ...
Sources of water pollution are either point sources or non-point sources. [155] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant or an oil spill. Non-point sources are more diffuse. An example is agricultural runoff. [156] Pollution is the result of the cumulative effect over time.
