1) The harm of air pollutants to human health is mainly manifested as respiratory diseases. For example, dust can stimulate the respiratory tract, causing bronchitis, bronchial asthma, emphysema, conjunctivitis, etc.; sulfur dioxide has irritating effects on eyes, nose, throat and lung; carbon dioxide has obvious stimulating effect on skin and mucous membranes, causing acute at high concentration Poisoning, headache, dizziness, severe coma, spastic tremors.

2) The main pollutants in salt plant wastewater are solid suspended solids, oils and acid-base waste. The hazard is to make the soil salinize, destroy the pollution source of the groundwater protective layer, affect the fishery production, destroy the growth of crops, and silt the river after sedimentation.
3) The hazards of noise include: affecting people's normal life, damaging hearing, causing neurasthenia, irregular heartbeat, loss of appetite, indigestion and other diseases, as well as affecting safe production and reducing labor productivity. 
Hazards from environmental pollution during salt production
NEST cell culture plates have round edges for better handling. Low profile, low-evaporation lid design assure uniform growth. Tissue treatedand non-treated are both available. Non-treated growth surface is more hydrophobic than tissue culture surface and are similar to the surfaceof a bacteriological Petri dish. Small feet on the bottom corners of each plate eliminate scraping of the microscope lens.
