According to a health science study published by Nature Newsletter on the 28th, scientists have evaluated a large data set and believe that exposure of mothers to very high levels of pesticides during pregnancy may lead to abnormal births. Take policy intervention.
The use of pesticides is one of the important measures to increase agricultural production. However, the serious problems exposed by many chemical synthetic pesticides during processing and use, as well as the serious environmental consequences after their application, did not gradually lead people until the mid-20th century. s concern. Past research has shown that pesticides can have a negative impact on the health of agricultural workers. Pesticide exposure can even affect human fertility, but it has been unclear what impact those people living near agricultural areas may be affected.
This time, Axis Lawson, a researcher at the University of California, Santa Barbara, and colleagues analyzed data from the San Joaquin Valley in California, which is dominated by agriculture. These data cover the birth record of 500,000 people and the use of local pesticides between 1997 and 2011. They want to investigate the relationship between pesticide exposure and bad births. For birth-related data, the research team focused on birth weight, gestational age, and birth abnormalities.
Studies have shown that if a mother is exposed to a very high dose of pesticide during pregnancy, the likelihood of a bad birth is increased by 5% to 9%. The research team proposes that policy interventions should be conducted in a timely manner for groups at greatest risk, or pesticide-related birth abnormalities can be reduced. In addition, because the research team is evaluating a large dataset from the San Joaquin Valley, this target group is also expected to benefit from policy measures aimed at reducing pesticide-related birth abnormalities.

Sun-Shading Net is a series of colored shade nets with special optical properties which improve the utilization of solar radiation by agricultural crops. This technology promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop. This is an economical and environmentally friendly alternative to current labor-consuming methods (such as pruning and thinning) and intensive use of growth regulators and other chemicals. ChromatiNet enables growers to control vegetative growth characteristics, such as leaf size, branch length and plant height in plants, as well as the rate of maturation and flowering. This enables adaptation to market preferences, with clear economic advantages.
Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
