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.
Contaminants of emerging concern (CECs) is a term used by water quality professionals to describe pollutants that have been detected in environmental monitoring samples, that may cause ecological or human health impacts, and typically are not regulated under current environmental laws.
Education on health and the dangers of lead mining is also being given to local people. [6] It is hoped that the clean-up can be completed prior to the start of the rainy season in July, which will spread contaminants, though it is being hampered by the remoteness of the villages and Muslim restrictions preventing men from entering some compounds.
The advent of oil production has also negatively impacted the Niger Delta region due to unprecedented oil spillage which has been ongoing for the past 5 decades making the region one of the most polluted in the world. [8] [9] The heavy contamination of the air, ground and water with toxic pollutants is often used as an example of ecocide.
Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients.It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. [1]
Sodium silicate with additives was injected into the ground to harden it and thereby to prevent further leakage of highly radioactive water from the Fukushima Daiichi nuclear power plant in Japan in April, 2011. [32] The residual heat carried by the water used for cooling the damaged reactors accelerated the setting of the injected mixture.
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
According to the World Bank, in 2010," water production facilities in Nigeria were rarely not operating to optimum capacity due to broken down equipment, or lack of power supply or fuel for pumping.” [18] The operating cost of water agencies is increased by the need to rely on diesel generators or even having to build their own power plants ...
