The accurate statement regarding toxic chemicals is that they can indeed be absorbed through the skin without protection. Many toxic substances, including certain solvents and chemical compounds, pose a risk not only through inhalation and ingestion but also through dermal exposure. The skin can act as a pathway for these chemicals to enter the bloodstream, leading to potential health effects. This underscores the importance of wearing appropriate personal protective equipment (PPE), such as gloves and lab coats, to minimize the risk of skin exposure when handling toxic materials.

In contrast, the other statements overlook the multiple pathways through which toxic chemicals can affect human health. For instance, some toxic agents can enter the body via inhalation, ingestion, or dermal contact, depending on their properties and the conditions of exposure. Claiming these chemicals can only enter the body through one method ignores the complexity of exposure routes. Additionally, the idea that their effects are limited to ingestion misrepresents the potential dangers of inhalation or dermal absorption. The statement about chemicals being harmless when placed in containers is misleading; while containment can reduce exposure, it does not eliminate the potential hazards of the substances contained. Therefore, it’s crucial to understand that toxic chemicals require careful handling and protective measures to prevent exposure through various routes.
