“ＰＭ2.5 乳児の脳に影響のおそれ” ユニセフ報告書
12月7日 4時37分
ユニセフ＝国連児童基金は、大気汚染物質ＰＭ２．５が幼い子どもの脳の発達を損ない、生涯にわたって影響が残るおそれがあるとする報告書をまとめ、中でも、汚染がひどく危険にさらされる子どもの数が多いインドなど、南アジア地域に対し早急な対策を呼びかけました。
ユニセフは６日、大気汚染が子どもの脳の発達に及ぼす影響について、報告書を発表しました。
それによりますと、大気汚染物質のＰＭ２．５は、粒子が極めて小さいため、血管を通って脳に到達し、脳細胞の炎症を引き起こしたり神経細胞の伝達に関わる部分を破壊したりして、学習や脳の発達の基礎となる部分を損なうおそれがあるということです。
特に脳が発達段階にある１歳未満の乳児など幼い子どもは影響を受けやすく、ＰＭ２．５の影響が生涯にわたって残るおそれがあると指摘しています。
報告書は、ＷＨＯ＝世界保健機関が定めた基準値の６倍以上にのぼる汚染レベルの地域に、現在、世界でおよそ１７００万人の乳児が暮らしていると推計していて、このうち７割にあたる１２２０万人が経済発展が著しいインドなど南アジア地域に集中しているとしています。
ユニセフはこうした地域の国々に対し、汚染濃度が低い時間帯での通学や、機能性の高いマスクの提供、それに学校や病院の近くに汚染源が存在しないよう都市計画を推進することなど、対策を早急に実行するよう呼びかけています。
My translation
UNICEF = United
Nations Children's Fund was
gathering a report which assumed that there was a fear that while the
atmospheric pollutant PM2.5 could damage the cerebral development of a young
child, its influence left behind was for a lifetime; it appealed for immediate
measures to be taken for the many children who were exposed to the risk of this
terrible pollution in India and other parts of South Asia.
On the 6th UNICEF
released a report about the influence of air pollution on a child's cerebral
development.
According to the
report there was a fear that because PM2.5 was an atmospheric pollutant of very small particle that could reach the brain through the blood vessels; and it could cause an inflammation of brain cells and destroy a part of the communication
of nerve cells. There was a fear that this would destroy the
brain’s foundation for future learning and cerebral development.
It pointed that a young child of less
than 1-year-old who was having a brain in the development stage was particularly tended to be affected, and the fear that the
influence of PM2.5 left behind could be
for a lifetime.
The report was
estimating that about 17 million babies in the world at present were living in
areas that had the contamination level 6 times above the standard set by the
WHO= the World Health Organization, and assumed that among these 12.2
million people representing 70 percent were concentrating in India etc. in
South Asia where economic developments were clearly noted.
Towards the countries
in these areas, the UNICEF was calling for an early implementation of policies in notifying the timing for going to school when
pollution density was low and offering high performance masks; and to promote urban planning so that pollutant sources would not exist near schools and
hospitals.
It is obvious that high economic growth carries a price.
