- 1. Start-stop tech powers battery innovation and market expansion
As the electric vehicle market could eventually boom, the best opportunity for vehicle batteries in the more immediate future in China is in start-stop technology and in the micro hybrid - a dual battery system that includes a lead-acid battery and a lithium-ion battery. - Micro hybrid batteries, with engine downsizing and powertrain boosting, can improve fuel economy by up to 15 percent, compared with conventional batteries. Johnson Controls estimates micro hybrid batteries could be adopted worldwide after 2020.

- 2. Blood lead poisoning
Several hundred children were poisoned by blood lead in Fengxiang Shanxi, China.- In 2009, the blood lead content of 615 children was higher than standard levels, and among them were 166 children with medium and high levels of lead poisoning. All of the above was due to the waste water, gas and residue which was produced by the local smelting company.
- 3. Nigerian lead pollution incident caused up to 250 deaths
In March 2010, illegal gold mining caused serious lead pollution which resulted in the deaths of as many as 250 people.- Nigeria's chief epidemiologist confirmed to the media that illegal mining activity in the area had caused at least 163 people to die from lead poisoning, mostly aged between 5 and 10 years. Experts from the world health organization were leading the local investigation.
- Nigeria's BBS newspaper quoted state health officials as saying the number of people hospitalized due to poisoning had risen to at least 450. All the cases were found in close proximity to a number of illegal gold mines in the area which operated without regard to normal regulations and procedures concerning lead, whose loss was not controlled, causing widespread water pollution. Local residents drinking the contaminated water displayed symptoms of poisoning afterwards. Now many people, fearing local poisoning, have fled their homes.
- The world health organization says more than 100 micrograms of lead per liter in human blood is harmful to health, especially affecting the nervous system and reproductive system, as well as causing great damage to the kidneys. Pregnant women and children are the most vulnerable group.
