Toxicity is the degree to which a substance can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity). By extension, the word may be metaphorically used to describe toxic effects on larger and more complex groups, such as the family unit or society at large.
A central concept of toxicology is that effects are dose-dependent; even water can lead to water intoxication when taken in too high a dose, whereas for even a very toxic substance such as snake venom there is a dose below which there is no detectable toxic effect. Toxicity is species-specific, making cross-species analysis problematic. Newer paradigms and metrics are evolving to bypass animal testing, while maintaining the concept of toxicity endpoints.
There are generally three types of toxic entities; chemical, biological, and physical:
Britney Jean Spears (born December 2, 1981) is an American singer and actress. Born in McComb, Mississippi, and raised in Kentwood, Louisiana, she performed acting roles in stage productions and television shows as a child before signing with Jive Records in 1997. Spears's first and second studio albums, ...Baby One More Time (1999) and Oops!... I Did It Again (2000), became international successes, with the former becoming the best-selling album by a teenage solo artist. Title tracks "...Baby One More Time" and "Oops!... I Did It Again" broke international sales records. In 2001, Spears released her self-titled third studio album, Britney, and played the starring role in the film Crossroads (2002). She assumed creative control of her fourth studio album, In the Zone (2003), which yielded the worldwide success of the "Toxic" single.
In 2007, Spears's much-publicized personal issues sent her career into hiatus. Her fifth studio album, Blackout, was released later that year, and spawned hits such as "Gimme More" and "Piece of Me". Her erratic behavior and hospitalizations continued through the following year, at which point she was placed under a still ongoing conservatorship. Spears's sixth studio album, Circus (2008), included global chart-topping lead single "Womanizer". Its supporting tour The Circus Starring Britney Spears was one of the highest-grossing global concert tours in 2009.
Baby, can't you see?
I'm calling a guy like you
Should wear a warning
It's dangerous, I'm fallin'
There's no escape
I can't wait, I need a hit
Baby, give me it
You're dangerous, I'm lovin' it
Too high, can't come down
Losing my head
Spinning 'round and 'round
Do you feel me now?
With a taste of your lips
I'm on a ride
You're toxic, I'm slipping under
With a taste of poison paradise
I'm addicted to you
Don't you know that you're toxic?
And I love what you do
Don't you know that you're toxic?
It's getting late
To give you up
I took a sip from my devil cup
Slowly, it's taking over me
Too high, can't come down
It's in the air
And it's all around
Can you feel me now?
With a taste of your lips
I'm on a ride
You're toxic, I'm slipping under
With a taste of poison paradise
I'm addicted to you
Don't you know that you're toxic?
And I love what you do
Don't you know that you're toxic?
Don't you know that you're toxic?
With a taste of your lips
I'm on a ride
You're toxic, I'm slipping under
With a taste of poison paradise
I'm addicted to you
Don't you know that you're toxic?
With a taste of your lips
I'm on a ride
You're toxic, I'm slipping under
With a taste of poison paradise
I'm addicted to you
Don't you know that you're toxic?
Intoxicate me now
With your lovin' now
I think I'm ready now
I think I'm ready now
Intoxicate me now
With your lovin' now
I think I'm ready now
