environmental group revealed the presence of heavy metals in some firecrackers
and pyrotechnic devices.
As part of its annual drive for a toxics-free celebration of Christmas and New
Year, the EcoWaste Coalition on November 22 and 25 bought 20 samples of
popular“paputok” and “pailaw” that have started to thrive in M. de Santos St.,
Divisoria as the festive holidays draw nearer.
The group then analyzed the 20 samples for heavy metals using a portable X-Ray
Fluorescence (XRF) equipment.
analysis was done in time for the Department of Health-initiated stakeholders’
meeting on “Firecrackers/Fireworks Injury Prevention Program” on
Results indicated significant levels of heavy metals such as antimony, barium,
chromium, copper and lead in the samples. Traces of mercury were also found in
These metals are often added to the black powder mixture of charcoal, sulfur,
potassium or sodium nitrate to create the desired sparkles and colors.
None of the samples provided details about their chemical ingredients,
particularly their heavy metal contents.
“While Republic Act 7183 provides for some safety and labeling requirements to
be followed, the law neither bans or restricts the use of toxic chemicals in
the production of firecrackers and other pyrotechnic devices, nor does it
compel manufacturers and distributors to disclose the chemical contents on the
product labels,” observed Aileen Lucero of the EcoWaste Coalition’s Project
“On top of the deafening noise and unsightly trash, the explosion of
firecrackers and fireworks creates a toxic cocktail of chemicals that is
indisputably bad for public health and the environment,” she said.
Lung expert Dr. Maricar Limpin confirmed that the “blasting of firecrackers and
other pyrotechnic devices yields greenhouse gases, metal oxides, particulates
and other pollutants that we inhale, affecting the lungs and other vital organs
such as the kidneys, heart and brain.” Limpin is associated with the Philippine
College of Chest Physicians and the Philippine Medical Association.
Out of 20 samples, lead, a potent neurotoxin and probable human carcinogen, was
detected in nine samples with a Diamond Fireworks “Great Small Magic
Scourge” showing the highest level at 6,481 ppm.
The other lead-positive samples include a Diamond Fireworks “Pilipao
Crackers” with 5,542 ppm lead, a Leopard King “Pili Cracker,” 2,869 ppm; a
Leopard King “Happy Ball” with 2,488 ppm lead;a Tiger Fireworks “Dragon
Eggs,” 2,361 ppm; a Tiger Fireworks “Pilipao Crackers,” 1,779 ppm; a Tiger
Fireworks “Dragon Egg Thunder,” 1,473 ppm; a Leopard King “Christmas Tree,”
1,235 ppm; and a Tiger Fireworks “Narcissus,” 172 ppm.
Barium was found in 17 samples with Tiger Fireworks 7″ “Sparklers”
registering over 100,000 ppm of both barium and copper, followed by a Diamond
Fireworks “Roman Candles” with 23,700 ppm barium and a Leopard King
“Christmas Tree” with 11,800 ppm barium.
Antimony, a possible human carcinogen, was detected in “Pulling Fireworks at
Chromium up to 666 ppm was found in four samples with Tiger Fireworks
“Festival”flaming balls showing the highest level.
Trace amounts of mercury, in the range of 2.2 ppm to 5.5 ppm, were detected in
Tiger Fireworks “Festival,” “Green Penoy,” “Happy Flower” and “Saturn
Missiles,” and in “Pulling Fireworks.”
Antimony, chromium, lead and mercury compounds are included in the Priority
Chemicals List of the Philippines, or chemicals that the Department of
Environment and Natural Resources “has determined to potentially pose
unreasonable risk to public health, workplace, and the environment.”
