Fly ash is a byproduct of coal combustion, and it is often used as a construction material. However, fly ash can also contain harmful pollutants, including trace metals.<\/p>\n<p>Antimony is a metalloid that is naturally found in the environment. It is also used in a variety of industrial applications, including batteries, semiconductors, and flame retardants. Antimony can be toxic to humans if it is inhaled or ingested. It can cause a variety of health problems, including respiratory problems, skin problems, and cancer.<\/p>\n<p>Cadmium is a heavy metal that is also naturally found in the environment. It is used in a variety of industrial applications, including batteries, pigments, and stabilizers. Cadmium can be toxic to humans if it is inhaled or ingested. It can cause a variety of health problems, including kidney damage, bone disease, and cancer.<\/p>\n<p>Arsenic is a metalloid that is naturally found in the environment. It is also used in a variety of industrial applications, including pesticides, herbicides, and wood preservatives. Arsenic can be toxic to humans if it is inhaled or ingested. It can cause a variety of health problems, <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n     <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div>        <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> including skin problems, nerve damage, and cancer.<\/p>\n<p>Exposure to harmful trace metals in fly ash can occur through inhalation, ingestion, or skin contact.
