What type of pollution affects a bloodworm?

Answer 1

Bloodworms, which are the larval stage of midge flies, are primarily affected by water pollution, especially from organic pollutants and heavy metals. Excess nutrients from agricultural runoff can lead to eutrophication, depleting oxygen levels in the water and harming bloodworm populations. Additionally, chemical pollutants like pesticides and industrial discharges can disrupt their habitat and overall health. As sensitive indicators of water quality, their presence and abundance can reflect the level of pollution in aquatic ecosystems.
