Answer: 

Lead is a toxic substance that is dangerous at very low levels. It is linked to impacts on the developing brain that can cause learning challenges lower IQ, and behavioural problems such as attention deficit hyperactivity disorder (ADHD) and increased aggression.

Since 1991 the lead content in paint has been greatly reduced. It is safest to assume there is lead in paint in your home if it was built before 1991.

The level of risk from lead is greater in homes built before 1978. The older the house, the more lead content the paint will contain. For example, paint from before 1960 may contain up to 50% lead, a level that will create extremely dangerous levels of lead in dust if such paint is disturbed.

Lead was used to make paint more durable. Hence, paint with a high lead content was used on exterior surfaces especially on porches, railings and windows and indoors on “high-traffic” areas or those needing to be frequently wiped down such as window sills and trim baseboards, door frames, radiators, and throughout kitchens and bathrooms. Good information is available to deal safely with lead paint.
