Most important symptoms/effects, acute and delayed

INHALATION OR INGESTION: Abdominal pain, loss of appetite, weight loss, constipation, apathy or irritability, vomiting, fatigue, headache, weakness metallic taste and muscle incoordination. Lead line on gums. EYES: Irritation. May cause corneal destruction. SKIN: Pain and severe burns. (USCG, 1999)


Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting.

LeadLead (/ˈlɛd/) is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82.
It is a heavy metal that is denser than most common materials.
Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air.
Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements.

SulfurSulfur (in non-scientific British use also sulphur) is a chemical element with the symbol S and atomic number 16.
It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8.
Elemental sulfur is a bright yellow, crystalline solid at room temperature.
Sulfur burns with a blue flame with formation of sulfur dioxide, which has a suffocating and irritating odor.
Sulfur is insoluble in water but soluble in carbon disulfide and, to a lesser extent, in other nonpolar organic solvents, such as benzene and toluene.
