An international team of researchers, including an Australian, say the safe storage of dangerous pesticides doesn't go far enough to protect the health of the public. They are calling for national bans in the hopes it will reduce the rate of suicide.

According to the World Health Organisation, self-poisoning using pesticides is one of the three most common means of suicide worldwide, and accounts for 14-20 per cent of all suicides. Many of these deaths occur in people who live in rural areas in low- and middle-income countries, making it a major public health problem in these regions.
