In recent years, pesticides have been widely used in agricultural production, but the used pesticide bottles have not been properly managed. Farmers use pesticides to discard packages randomly in the fields, ponds and rivers, and residual pesticides in waste packaging are The hot summer season naturally volatilizes or rushes into the ground through rainwater, causing water quality and soil pollution, which directly endangers human health, or passes through the progressive accumulation of the food chain, and ultimately threatens people's health. In rural areas, human poisoning due to consumption of agricultural products or other foods contaminated with pesticide waste and death from livestock and poultry poisoning have occurred from time to time. Moreover, these plastic packaging bottles and bags containing polymer resins are not easily degraded in the natural environment and may remain for 200 to 700 years, causing serious chemical pollution to the soil environment and greatly affecting the growth of crops. After the broken glass bottles are broken, there are farmers who may scratch the ground at any time.
In 2009, Beijing launched the "Beijing urban modern agriculture infrastructure construction and comprehensive development plan." The idyllic cleaning and recycling project in the plan is mainly to improve the quality of the agricultural environment in the capital, to implement the recycling of waste pesticide packaging, and to dispose of the waste pesticide bag. , bottles, barrels, etc. for fixed-point recovery, classification, the city unified destruction.
Not long ago, in a compound in Xuguantun Village, a county town in Tongzhou District, Beijing, farmers lined up long queues and handed over waste pesticide packaging from the fields to the collection point. This is a scene seen by reporters at the implementation site of the "Pesticide Bottle Waste Recycling Project" at Beijing Plant Protection Station. Every two weeks there is such a gathering day. It is very popular among farmers. They have not only found a place for pesticide bottles that they could not handle in the past, but they can also switch from collection points to everyday items such as soap powder and soap that are commonly used in the home. .
Beijing Plant Protection Station set up a demonstration site in Tongzhou District and actively explored the replacement of pesticide bottle waste with replacement of materials. They used their leisure time in autumn and winter to conduct extensive publicity to raise farmers' awareness of the environment and allow farmers to fully recognize the hazards of throwing pesticide bottle waste on the environment and personal safety. At the same time, they told farmers how to properly dispose of the waste of pesticide bottles, and encouraged them to hand over the waste packaging to the collection point by way of replacement. The plant protection department assisted the farmers to centralize the disposal of pesticide bottle waste.
At present, village committees that pay for the replacement and recovery of model villages have expressed a keen interest in the replacement of the project. Farmers are more welcome. The Tongzhou District Plant Protection Department took the lead in setting up three recycling demonstration sites in the industrial belts of the county and townships, and adopted a paid replacement method for recycling. The recovered wastes were registered, classified and sent to the Plant Protection Station for harmlessness. deal with. The work was carried out for more than five months. Yang Baochun, the head of Xuguantun Village demonstration site in County Township, said: “The village is located in the suburbs, and it is planted with greenhouse vegetables for a long time. Pesticides are used in large quantities. In the past, pesticide bottles used by farmers were readily available. In the ground or in the rubbish dump, many packages were thrown into the ground for many years, which not only polluted the land, but also sometimes contaminated the vegetables produced. Now, the village collects it once every two weeks and sorts it out while recycling. On the same month, they packed their own land and packed them, and some also mobilized the relatives and friends of the surrounding villages to pick up the waste to replace them.They used their packaging to replace a bag of detergent with 20 packages and to change the soap used daily in the home. According to the introduction of plant protection personnel from t towns, the project started, three demonstration sites in the town and 15 surrounding natural villages. As of now, 326,000 waste pesticide bottles have been recovered, and waste packaging materials recovered have been recycled. Some were discarded more than 10 years ago. Nowadays, farmers in county towns and villages have changed the habit of discarding pesticide waste in the past, raising awareness of environmental protection.
The reporter saw at the project site that, after publicizing the activities of the previous period, the awareness of environmental protection of the local farmers was obviously strengthened, and the recycling workers and the farmers who sold the products had a strong sense of self-protection. The recycling workers wore protective clothing and rubber gloves. The farmers We also wear protective gloves. In the afternoon of the same day, the recovered pesticide packaging was loaded onto a car and was sent to the Beijing Cement Factory in Xiaoying Village, Machikou Town, Changping District, where it was burned and destroyed. The reporter learned to understand the whole process. In the blazing flames, the pesticide waste packaging was quickly disposed of. Xiao Xu of the Phytosanitary Section of Beijing Plant Protection Station told reporters that at the end of last year and in the first half of this year, activities like this had been carried out several times, and the city had cumulatively destroyed 2.3 million packages of pesticide waste. The person in charge of this destruction work at the Beijing Cement Plant Jinyu Honglin Environmental Protection Technology Co., Ltd. also told reporters: “We are here to undertake more than 3,000 enterprises, research, health, chemical and other units in the city, 28 types of toxic We will be able to destroy the hazardous wastes and destroy them after 24 hours."
According to the person in charge of the Beijing Municipal Bureau of Agriculture, the amount of pesticides used in Beijing in 2008 reached more than 4,000 tons (commodity volume), and about 80-200 tons of pesticide bottle waste was generated, resulting in about 3 million packages of waste pesticide products. The implementation of the field cleaning cycle project will achieve no exposed pesticide bottle in the demonstration area, and gradually drive non-demonstration areas and the city. The Plant Protection Station will cooperate with the municipal pesticide management unit to establish a recycling registration system for container packaging after the use of highly toxic pesticides, implement a paid recycling and centralized disposal system for pesticide bottle waste, reduce non-point source pollution in rural areas, and ensure the quality and safety of agricultural products. , protect the ecological environment, promote environmental protection and sustainable development of agriculture. Based on the implementation of the project, it actively explored the management methods for pesticide bottle waste and established a long-term mechanism for recycling.
Proper lighting is essential for the health and well-being of reptiles kept in captivity. Reptiles require specific lighting conditions to mimic their natural habitat and provide them with the necessary light and heat for various physiological functions.
The lighting for reptiles offered by reputable brands such as GAKO Aquatics comes with a range of features to ensure the optimal care of your scaly companions. One key feature is the inclusion of UVB lighting, which is crucial for reptiles to synthesize vitamin D3 and metabolize calcium effectively. This promotes strong bone development and prevents common health issues like metabolic bone disease.
Another important feature is the provision of UVA lighting, which enhances reptiles' natural behavior and stimulates appetite. It also contributes to their overall well-being and helps regulate their circadian rhythm.
Furthermore, high-quality reptile lighting options often offer adjustable heat settings, allowing you to create a thermal gradient within the enclosure. This ensures that your reptile can move between warmer and cooler areas to regulate their body temperature as they would in the wild.
