Which of the following is considered toxic industrial waste?

Pesticide wastes are considered toxic industrial waste because they contain harmful chemicals designed to kill pests and can pose significant risks to human health and the environment. These substances may have acute toxicity, leading to immediate harmful effects upon exposure, or chronic toxicity, resulting in long-term adverse effects from prolonged exposure. The disposal of pesticide wastes must adhere to strict regulations to prevent contamination of soil and water sources, further emphasizing its classification as toxic industrial waste.

In contrast, food scraps are organic materials that can be composted, cement residues are typically non-toxic and can be recycled or reused, and plastic packaging, while environmentally problematic, does not necessarily contain toxic substances in the same way that pesticide wastes do. The potential for direct harm due to the chemicals found in pesticides highlights the critical need for careful handling and disposal practices, reinforcing their designation as toxic industrial waste.
