Samples are sent to laboratories, which analyse levels of certain types of bacteria that could indicate the presence of pollution, primarily from sewerage or livestock waste.
Plastic pollution generated on land flows into and accumulates in our oceans. One of the 11 major oceanic gyres worldwide is the North Pacific Gyre, or as most commonly known the Great Pacific Garbage Patch, spans an area roughly twice the size of the United States.
From Jiling to Guangdong, Jiangsu to Yunnan, industrial centers across China have been embroiled in a spate of water calamities whose damage and frequency are staggering.
“Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, biomagnify in food chains, and to have potential significant impacts on human health and the environment”
Although New Zealand is well-known for its pristine nature and plentiful water resources the majority of its water systems are becoming increasingly polluted due to agricultural run-off and mismanagement.
