We rarely think about the dangers of things around us. Scientific research shows that some of them emit harmful substances. Rambler will talk about toxic objects and provide research data explaining why they are dangerous.
Plastic plates and containers
Polycarbonate plastic materials – bottles, containers, children's dishes – often contain Bisphenol A (BPA). When heating or storing acidic/hot foods, BPA can be released and enter the body. The link between BPA levels in the body and an increased risk of metabolic and hormonal disorders, cardiovascular disease and reproductive problems has been documented in several studies, one of which was conducted by Harvard School of Public Health. Therefore, plastic dishes, especially those exposed to hot water, should be replaced with glass, ceramic or stainless steel.
Candles and air scents
When burning scented candles, substances such as formaldehyde, benzene and toluene are released – carcinogens that irritate the respiratory system. Meanwhile, air fresheners and scented sprays often release VOCs that reduce indoor air quality, especially if the air is poorly ventilated. For this reason, candles and aerosols should be used rarely, and the room should be ventilated as often as possible; For aroma, it is better to give preference to essential oils with a diffuser or natural phytozone.

Cheap LED bulbs and potential toxic risks
At first glance, LED lights are safe, energy efficient and durable. But this is only true for certified models. Cheap lights made from unsafe materials can emit toxic substances or create annoying flickering lights. According to work published in the magazine Environmental Science & TechnologyCheap LED lights, when the shell is damaged, will release heavy metals – lead, copper, nickel. Therefore, you should not save on them.
Old furniture, carpets, synthetic fabrics
Many upholstered furniture and carpets release VOCs from adhesives, paints and impregnations – formaldehyde, styrene and others. In addition, carpets and upholstered furniture actively accumulate dust, microparticles, pesticides, pieces of skin, hair, which will fly into the air in the column at the slightest movement. So, when buying new furniture, choose products made from natural materials, wet clean them regularly and avoid carpeting in the bedroom – especially if you have allergies.
Cleaning products and household chemicals
Many detergents and household cleaners contain harsh chemicals that, when sprayed or rinsed off, can create fumes and microscopic particles that can irritate the respiratory tract. Such reactions have been noted in studies comparing health indicators of people who regularly use household chemicals and those who do not. To protect yourself, use products with minimal ingredients, wear gloves, and ventilate the room immediately after cleaning.
Plastic bottles can be recycled
Plastic, especially old or hot plastic, will release chemical compounds. Water stored in plastic for a long time can contain harmful impurities. When bottles are reused, chemicals and bacteria enter the water through small cracks. It is better to use glass or steel bottles and do not store water in plastic bottles for long periods of time.
Old electrical equipment and wiring
A significant portion of home fires are caused by electrical faults, overloads, overheated connections, and weak wiring. According to official statistics, faulty electrical equipment causes about 26% of fires. It is important not to overload the extension cord, monitor the condition of the cable, turn off the device when not in use, and use an outlet based on the device's power source.
Teflon-coated kitchen utensils
Teflon pans are safe to cook over medium heat. But research shows that at extreme temperatures above 260–300 °C, Teflon begins to decompose, releasing perfluorinated compounds – mainly perfluorooctanoic acid (PFOA). A report by the US Environmental Protection Agency (EPA) states that PFOA is a persistent organic pollutant that stays in the body for many years.
