(tumorgenic) based on animal data.
Special Remarks on other Toxic Effects on Humans: Acute Potential Health Effects: Skin: May cause skin
irritation. Eyes: Dust may cause mechanical irritation. Inhalation: May cause respiratory tract irritation.
Ingestion: Harmful if swallowed in large amounts. May cause gastrointestinal (digestive) tract irritation with
epigastric pain, abdominal cramps, nausea, vomiting and diarrhoea. Affects metabolism and cardiovascular
system with symptoms including increase in metabolism, flushing, palpitations, rapid heart rate, dysrhythmias,
hypotension, blood pressure elevation and weight loss, metabolic acidosis. May affect brain and
behaviour/central nervous system. Symptoms may include nervousness, anxiety, restlessness, insomnia,
dizziness, tremor, seizures, convulsions, hallucinations, somnolence, toxic psychosis, tremors, convulsions,
ataxia. May also affect blood, respiration (hyperventilation), and urinary system (mild increase in urinary
volume and urinary sodium excretion), and may directly produce hypokalemia. Chronic Potential Health
Effects: May cause cancer (tumorigen) based on animal studies. May cause reproductive and foetal effects. May
cause digestive tract disturbances (increased gastric acid, and pepsin secretion and a decrease in lower
oesophageal sphincter pressure), cardiovascular disturbances. Since it is a CNS stimulant, it may also affect the
Central Nervous System (CNS).

The first expression of this emerging culture were the broder-zinger, soloperformers and troupes of singer-songwriters who performed songs and skits in the secular sur-roundings of the inns, wine cellars and restaurant gardens of Jewish centers in Austro-Hungary,Romania and Russia. The broder-zinger were generally maskilim, followers of the haskalah, the
Power from the sun Free solar energy for generating power using photovoltaics As renewable energy systems have become more widespread, consumers and end users have become increasingly keen to generate their own electricity. Today, an efficient photovoltaic system offers the opportunity to make proﬁtable use of free solar energy. By installing photovoltaic modules, users demonstrate their
