ABSTRACT
Nowadays, parents' needs are increasing to choose toys, especially painting colors, that are both beautiful, ensure their children's health, and are also environmentally friendly. In the production of industrial painting colors, waste from steps in the watercolor production line, if not treated to meet environmental standards according to regulations, will become a huge hazard to the environment and human health. human. Including causing skin, eye, digestive, and respiratory allergies. Causes poisoning, disease, cancer... Destroys the aquatic environment, trees, pollutes rivers and lakes. When building an industrial painting colors production line and putting it into use, if you do not think about solutions to treat wastewater from the production process, it will not be able to operate long term. Wastewater from color factories is mainly heavy metals contained in painting colors such as lead carbonate, oxide, and metal salts containing cadmium chromate. These substances cause mass death of organisms in the water, and polluted water cannot be used for agriculture. This research uses two main methods: experimental research to create products; combined with the questionnaire survey method to get customer opinions after using the painting colors test. Research results show that painting colors products made from fruits and vegetables combined with beeswax and coconut oil are very eye-catching and receive positive feedback from customers. With the im of protecting children in the future and responding to the green environmental message in the world, we hope that safe painting colors products from vegetables and fruits will be popularized in the community in the future.
Keywords: vegetables, painting colors, environmental protection, safe products, beeswax.
The wastewater treatment plant is an extremely important infrastructure to ensure the quality of life, water use of human life, and other ways to ensure water quality for the natural environment. In the operation of it, there are always potential hazards affecting the health of the workers working in the factory. The study was performed using the Semi-quantitative risk assessment method to calculate the values of operational risks in the water treatment plant (WWP). The results of the study obtained 18 high potential hazards that may lead to the present in the water treatment process. The hazards were the leakage of deodorizing towers and the generation of toxic emissions of dead microorganisms that have the highest value with a risk scale of 20 points- frequent impacts on employees. The study has also identified the dangers present in WWP and this will be the premise for mitigating solutions for problems occurring at its.
