Introduction
0.1 Lead is a toxic heavy metal, has a wide range of industrial uses, but no known nutritional value. FAO/WHO joint
The Committee of Experts on Food Additives (JECFA) has conducted several assessments of the toxic effects of lead in food. Relatively low level of long-term violence
Exposure to lead can cause kidney and liver damage, disrupt the reproductive system, cardiovascular system, immune system, hematopoietic system, nervous system and
Gastrointestinal system. Short exposure to large amounts of lead can cause gastrointestinal pain, anemia, brain disease and even death. Low-level lead exposure is the most serious
The impact is a reduction in children's cognitive and intellectual development.
0.2 Lead exposure can occur through food and water sources, also in the workplace, through amateur activities or through exposure to lead contamination
The soil and air occur.
Lead contamination in foods comes from a variety of sources, including air and soil. Atmospheric lead from industrial pollution or leaded gasoline can pass through
Deposits on crop plants contaminate food. Sources of lead in soils include lead-containing ordnance, air guns or other military stored in previous arms stores
Improper use of munitions, pesticides and fertilizers, as well as sewage sludge. Lead in the soil can be deposited on the surface of the plant or taken through the soil
Into contaminated crop plants. Contaminated plants and soil subsequently become sources of livestock pollution.
0.4 Water is also one of the sources of lead contamination in food. Surface water can be contaminated by surface runoff (drainage) and atmospheric deposition
Lead contamination of surface water sources in the Ministries may be caused by leaching lead from hunting ammunition or fishing plumb bobs. Polluted surface water is aquatic
Potential sources of contamination of food animals. For drinking water and water used in food processing, plumbing or lead-containing devices are used in the piping system
The main source of pollution.
0.5 Food processing, handling and packaging processes may also cause lead contamination in food. Lead sources in the food processing sector include lead-based coatings
Materials and lead-based equipment, such as plumbing and lead-soldering equipment. In the field of food packaging, lead-free food cans have been identified as very important food
Lead pollution sources. Potential sources of contamination for other food packaging materials include colored plastic bags and bags that contain lead or lead dyes
Paper loading, lead-lined wine bottle caps, lead-glazed ware for packaging or storing food, lead glass or lead-containing metal containers.
0.6 The world is working to reduce lead contamination in food. The measures taken are focused on the following. Food and food additives
Lead is allowed to a limited standard, lead-free food cans are stopped (especially for baby food), lead levels in water are controlled, and lead content is reduced
Lead in the device is dissolved or restricted for use in decorative containers for research purposes and in food or dietary supplements
His source of lead pollution. Although measures to reduce lead pollution in the environment (such as reducing industrial releases of lead and limiting leaded gasoline
Use) is not specific to food, but these measures also help to reduce lead levels in food.
0.7 The International Codex Alimentarius Commission, the Intergovernmental Cooperative Organization and many countries have set limits on lead allowances for different foods.
Due to the ubiquity of lead in modern industrialized society, low levels of lead in food may be unavoidable. However, follow good agricultural practices and good
Good manufacturing practices can minimize lead contamination in food. Since many effective measures to reduce lead pollution depend on consumer behavior,
Therefore, separate chapters are also included in this guidance document to provide recommendations for adjusting consumer behavior.
Code of Practice for Preventing and Reducing Lead Pollution in Food
1 Scope
This guidance sets out the code of practice for preventing and reducing lead contamination in foodstuffs.
This Guidance Document is applicable to agricultural production, drinking water supply, food ingredient and processing, food packaging/storage material in the diet supply chain
The production and use of raw materials, prevention and reduction of lead pollution in food consumption behavior.
2 Recommended operating points based on good agricultural practices and good manufacturing practices
2.1 Agricultural Production
2.1.1 Leaded gasoline is a major source of lead contamination in the atmosphere. National government departments should take measures to reduce or prohibit agricultural areas
Use leaded gasoline.
2.1.2 Agricultural land near factory facilities, highways, weapons stores, air-gun shooting ranges and military shooting ranges will be far
Regions contain higher levels of lead. The land near the weathered buildings of exterior paint also contains high levels of lead,
Special attention should be given to the presence of such buildings. Whenever possible, farm operators should approach the source of lead or suspect that the level of lead has risen
Land for lead content testing to determine whether the lead content exceeds the local government departments on the planting of lead in the recommended value.
2.1.3 Farmers should avoid planting land that has been contaminated with lead arsenate (such as previous orchards)
Carrots or other root crops) or surfaces (such as leafy vegetables) that accumulate lead.
2.1.4 Treated sewage sludge land, if the sewage sludge does not meet the maximum allowable limits set by the national government departments, farm management
People should avoid using the above land to grow crops.
2.1.5 Leafy vegetables are more susceptible to the deposition of lead in the air than non-leafy vegetables or root vegetables. It is reported that cereals
Crops also absorb lead from the air at an appreciable rate. In areas where the level of lead in the air is high, farm operators should consider planting options
Relatively less susceptible to lead deposition in the air affected crops.
2.1.6 Farm operators should avoid the use of lead compounds (such as lead arsenate pesticides) or compounds that may be contaminated with lead in agricultural areas
(Eg improperly formulated copper salt fungicides or phosphate fertilizers).
2.1.7 Drying units driven by leaded gasoline can cause lead contamination of the dried crops. Farm operators and engaged in drying operations
Workers should avoid using lean gasoline-driven drying devices or other equipment to process harvested crops.
2.1.8 Crops should be protected during transport to processing facilities to avoid contamination by lead (eg exposure to the atmosphere
Lead, soil, dust).
2.1.9 Household or small commercial gardens should also take measures to reduce lead pollution. Avoid construction on highways and painted with lead paint
Planting nearby. If there is a high level of lead in the area where the farm is located, soil should be tested before planting.
Good agronomic measures that can be taken for a soil with a slight increase in lead levels include the incorporation of organic matter in the soil, the adjustment of the pH of the soil
Reducing the availability of lead to plants, selecting plants that are less susceptible to lead contamination, and using bushings to reduce soil contact on plants
product. In some areas, lead levels are not suitable for planting in the garden. Seedbed beds can be built with lead-free soils in these areas. If possible, park
Farmers should consult with local agricultural service agencies about what it means to plant too high levels of lead in the garden and how to treat it on lead-contaminated soil
Secure garden planting for advice.
2.1.10 Agricultural irrigation water should be protected from lead sources and lead levels monitored to prevent or reduce crop contamination with lead.
For example, well water used for irrigation should be properly protected to avoid contamination and be routinely monitored.
2.1.11 Local and national government agencies should inform farmers about the appropriate measures to be taken to prevent lead contamination of farmland.
2.2 drinking water
2.2.1 National government departments should consider setting limits on the amount of lead in drinking water or establishing appropriate control measures for lead in drinking water.
