What are the risks of BPA

PA (bisphenol A) may cause multiple hazards to the human body and the environment, specifically as follows:
Harm to human body
Affect the endocrine system
Interference with hormone function: BPA has a similar effect to estrogen, and may bind to estrogen receptors after entering the human body, simulating or interfering with the normal function of endogenous hormones, and then affecting the endocrine balance of the human body. For example, it may cause menstrual cycle disorders in women, affect ovulation, and increase the risk of breast cancer, endometrial cancer and other diseases; For men, it may interfere with the role of androgens, affect the development and function of the reproductive system, such as reducing the quality and quantity of sperm, and increase the incidence of prostate diseases.
Influence on thyroid function: studies have shown that BPA may interfere with the synthesis, transportation and metabolism of thyroid hormones, affect the normal function of the thyroid, and then have adverse effects on human growth, development, metabolism, such as causing abnormal thyroid hormone levels, causing goiter and other diseases.
Endangers reproduction and development
Abnormal embryonic development: Pregnant women are exposed to BPA, which can enter the fetus through the placenta and interfere with normal fetal development. Studies have found that exposure to higher levels of BPA during pregnancy may be associated with birth defects such as neural tube defects and abnormal heart development in the fetus.
Developmental problems in children: Children are more sensitive to BPA, and long-term exposure may affect their brain and nervous system development, leading to cognitive, learning and behavioral problems. For example, it may cause children to have symptoms such as inattention, hyperactivity, learning difficulties, and may also affect the development of the child's immune system, making the child more susceptible to diseases.
Cancer risk: Some studies suggest that long-term exposure to BPA may increase the risk of certain cancers. Animal experiments have shown that BPA may promote the growth and proliferation of tumor cells, and there is a certain association with the occurrence and development of breast cancer, prostate cancer, liver cancer and other cancers, but the direct causal relationship between BPA and human cancer is not completely clear, and further research is still needed.
Other health problems
Cardiovascular diseases: BPA may increase the risk of cardiovascular diseases by affecting the function of vascular endothelial cells and interfering with lipid metabolism, such as causing elevated blood pressure, dyslipidemia, and promoting the formation of atherosclerosis.
Diabetes: Studies have found that BPA exposure may be associated with increased insulin resistance, abnormal blood sugar regulation, and an increased risk of type 2 diabetes.
Harm to the environment
Contamination of water: BPA may enter the water environment during production, use and disposal. Due to its certain water solubility and stability, it is difficult to degrade rapidly in the natural environment, and will accumulate in the water body, causing harm to aquatic organisms, such as affecting the reproduction, development and behavior of fish, reducing the reproductive ability and quality of life of aquatic organisms, and destroying the balance of aquatic ecosystems.
Soil pollution: When waste or sewage containing BPA is discharged into the soil, BPA will adsorb on the surface of soil particles, affect the physical, chemical and biological properties of the soil, inhibit the activity and growth of microorganisms in the soil, and then affect the ecological function of the soil and the growth and development of plants, resulting in a decline in crop yield and quality.
Bioaccumulation: BPA has a certain degree of bioaccumulation, which can be gradually accumulated and amplified in organisms through the food chain. After low-nutrient organisms absorb BPA in the environment, they will be predation by high-nutrient organisms, thus increasing the concentration of BPA in organisms, causing greater potential harm to organisms at the top of the food chain, including humans.
