How to prevent childhood lead poisoning by
intervention at the seven points in the Lead Flow Chart:
Even though you may only have inquired about one aspect of lead poisoning
prevention, we are providing information on numerous aspects of the problem, in the hope
that you will find the holistic approach useful, and that you will realise how powerful
you are personally in reducing the toxic chemical load on people (especially children) and
the environment, now and in the future.
Point 1: Petrol
Surfaces. Australia reduced the amount of lead in petrol in 1993
and phased out leaded petrol by 1st January 2002 but stopping the flow of lead
from petrol into the environment does nothing to reduce the historical lead contamination
from petrol. Australia reduced the amount of lead in petrol in 1993
and phased out leaded petrol by 1st January 2002 but stopping the flow of lead
from petrol into the environment does nothing to reduce the historical lead contamination
from petrol.
- Do not undertake servicing or dismantling of
old cars on your property;
- Avoid homes or child-care within 10-20 m of
major roads;
- Lead from petrol and other sources builds up
in the ceiling dust in old houses and can be an ongoing source (through cracks, ceiling
roses, etc) or sudden source (if the ceiling falls down or is demolished) of lead
contamination of house dust. Leaded ceiling dust is just another reason (apart from leaded
paint) that renovation is the most likely cause of childhood lead poisoning. See the NSW
government factsheet "Lead Safe: Lead in Ceiling Dust". See the website
of the Australian Dust Removalists Association (ADRA), www.adra.com.au for specialists in ceiling dust
removal, in NSW. Do not attempt ceiling dust removal yourself.
Point 2: Paint
Surfaces - to stop lead particles from paint getting onto
surfaces that children might touch: - to stop lead particles from paint getting onto
surfaces that children might touch:
- Test for lead in any pre-1970 deteriorated paint (see Point 4 for test
procedures);
- Use barrier methods and consistent clean-up until safe removal can be
organised;
- Negotiate a contract with a professional renovator with experience
(preferably training) in lead paint removal to remove lead paint hazards, guaranteeing no
dispersal of lead, and approved disposal of contaminated debris;
- Protect children, women of reproductive capacity and pets from
renovation works. See the two booklets "Lead alert: 6 Step Guide to
Painting your Home": and " Lead Safe - A Renovator's Guide To The
Dangers Of Lead "
- Call on your state parliamentarians to institute training and licensing
for lead abatement (paint removal) contractors and lead assessors, and for Certificates of
Lead Safety for houses and childcare premises.
Point 3: Industry
Surfaces
- Avoid homes and child-care near lead industry;
- Reduce your use and purchase of all lead products and lead-containing
products like cars and contribute to maximum possible recycling rates for lead, e.g. car
batteries, light bulbs, flashing, pipes, wheel balancing weights;
- As lead is one of the toxic emissions from coal burning power stations,
reduce your electricity use.
Point 4: Surfaces Hands. Whether the source is petrol, paint or industry, the
major pathway of lead poisoning is via soil and dust (residual) contamination, to surfaces
and then from hands to mouth. To stop lead getting from surfaces to hands:
- Have your home or childcare centre assessed for lead contamination. See
the list of NSW lead assessors at www.lead.org.au/clp/assessorsnsw.html
or if you suspect that you know the source of lead and do not want to engage an assessor
to come out to the house,
- phone JBS on 02 8338 1011 and purchase a
Do-It-Yourself
Lead Safe Test Kit with sampling instructions for sending soil, dust or
paint for lead content analysis to Sydney Analytical Laboratories. This is an independent
NATA accredited lab which then sends the results to JBS who writes you an interpretation
and plan for reducing lead risks. Lead test kits which change colour to show if lead is
present in paint or ceramics etc are available from some hardware stores and paint trade
centres.
- Industrial HEPA vacuum, wet down and then remove old carpets, replace
with washable hard surfaces;
- Carpets which remain, and drapes and soft furnishings can be deleaded on
the surface by Elite
Maintenance Service Pty Ltd (ph 131580). Carpets should be vacuumed with a
HEPA-vacuum or when children are out of the room, and Elite-cleaned every 3 months. Do not
put vacuum cleaner dust in your compost or worm farm;
- Wet wipe, using liquid sugar soap and a sponge or mop, all hard surfaces
your child may contact, at least fortnightly, and preferably twice weekly or even daily
during the crawling phase;
- Stop track-in of dust or soil by placing washable mats or wet towels at
the front and back doors;
- Cover bare soil with grass or more permanent barriers like rubber mats
that let the grass grow through, gravel, etc;
- Mop paths, verandahs. See the fact sheet "Lead Aware
housekeeping and childcare"
and "Lead Poisoning - A Guide For Families"
at
- Before purchasing a house which is likely to be lead contaminated, have
a lead assessment done and negotiate a fair price for the house taking into account the
cost of remedying lead hazards.
Point 5: Hands
Mouth
- Wash children's hands constantly;
- Use a brush to clean under fingernails;
- Don't allow children to eat away from the table;
- Pin dummies to clothing;
- Ensure supervision sufficient to prevent the child eating old paint or
contaminated soil.
Point 6: Mouth Blood. Many individual factors influence what percentage of the
lead that is eaten is absorbed from the gut, e.g. an empty stomach absorbs far more lead
than a full one, children absorb 5 times more of the lead in the gut than adults. To
minimise lead absorption:
- Ensure adequate iron, calcium, zinc, Vit C, protein and omega 3 fatty
acids in the diet, especially iron (see "Are you getting enough iron?"
and "Is your baby getting enough iron?");
- Ensure that fatty fast foods (high in omega 6 fatty acids) are not
consumed too frequently;
- Stick to the good food pyramid.
- Ensure children have frequent small meals, especially before playing in
the morning.
- Testing the blood for lead is the best way of assessing recent exposure
(over the last 3 months) to lead. See "Rotary
CHILDHOOD LEAD EXPOSURE RISK FACTOR QUESTIONNAIRE & MESSAGE TO DOCTORS"
by The LEAD Group. To gain some understanding of the wide range of health effects of
increasing blood lead levels, see the factsheet: "Health Impacts of Lead Poisoning"
Point 7: Blood
Bones and Teeth
- Fruits with lots of pectin eg apples and pears, MAY reduce blood lead
levels, ie after lead has already been absorbed from the gut. Eating fruit with lots of
pectin can't hurt;
- Ensure prospective parents' blood lead levels are normal (below 10
µg/dL) before a baby is conceived, and for men for 4 months before a baby is conceived in
order to avoid fertility problems or passing on lead to the foetus;
- Testing children's shed baby teeth for lead is the best way to assess
the child's lead exposure at the time of the development of the teeth, which happens to
coincide with the early years of life when children are high-risk for ingesting and
absorbing lead and high sensitivity to the effects of lead. Tooth lead analysis
Hair lead tests are uninterpretable.
